"WILLIAM HENRY SWAN, OF KANKAKEE, ILLINOIS.

CHURN-DASH ER.

SPECIFICATION forming part of Letters Patent No. 634,377, dated October3, 1899 Application filed MaylZ, 1899.

To all whom it may concern:

Be it known that 1, WILLIAM HENRY SWAN, of Kankakee, in the county ofKaukakee and State of Illinois, have invented a new and ImprovedChurn-Dasher, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a churn-handle with a set ofrotary dashers so constructed that in churning the dashers will rotatein opposite directions and the motion of the dashers be reversedautomatically by the up-and-down movement of the handle.

Another object of the invention is to provide a simple and economicchurn-dasher that will not splash the cream, thus enabling the churn tobe filled nearly to the top.

A further object is to provide a construction of dashers that may bekept perfectly clean and the lower dasher be mounted to rotate at thebottom of the churn.

Another object of the invention is to so construct the dashers that theymay be quickly and conveniently placed upon the handle or removedtherefrom.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of a portion of the handle and two dashersmounted thereon. Fig. 2 is a horizontal section through the handle,taken on the line 2 2 of Fig. 1, showing the lower dasher andspacing-block in plan view; and Fig. 3 is a side elevation of the lowerportion of the handle, the dashers having been removed.

The handle A is reduced in diameter atthe bottom, forming a lowershoulder 10 and an upper shoulder 11, and centrally between these twoshoulders the handle is reoessed at both sides, forming a fiat section12 between an upper cylindrical section 13 and a lower cylindricalsection 14. The dashers employed are usually two in number, B and 0,although a single dasher maybe used, if desired. Each dasher is made intwo sections, the sections of the lower dasher B being designated as band b and the sections of the upper dasher Serial No. 716,574. (Nomodel.)

C as c and a. Each section of the lower dasher B consists of a squarehub 15 and blades 16, that extend from opposite sides of the hub. Theseblades are inclined in oppo- Site directions, and the opposing faces ofthe hubs of the sections 1) and h are provided with recesses 17, asshown in Fig. 1, whereby the hubs of the two sections are interlocked,one section being at right angles to the other. A recess 18 is made inthe bottom surface of the hub of the lower dasher B, which recess (shownin Fig. 1) is adapted to receive that portion of the handle below theshoulder 10, and the lower hub is therefore adapted to restupon the saidshoulder, since the hubs are provided with a central opening of greaterdiameter than the diameter of the cylindrical section 14 of the handle.Thus it will be observed that the bottom of the lower dasher will be atthe bottom of the handle, and the dasher may be brought close to thebottom of the churn.

The sections of the upper dasher C are illterlocked in like manner asthe sections of the lower dasher B, and each section consists of a hub19,having a central opening of greater diameter than the cylindricalsurface 13 of the handle, and blades 20, extending from opposite sides,the said blades of each section being oppositely inclined, and theblades of the upper dasher O are at an angle to the blades of the lowerdasher B. The hubs of each dasher are provided with a diagonal slot 21,extending from a point between the blades and connecting with thecentral opening of the hubs, as shown in both Figs. 1 and 2. A recess 21is made in the upper surface of the upper hub of the upper dasher O, andthis recess is adapted to receive that portion of the handle A that isjust above the upper shoulder 11.

The dashers are placed upon the handle by entering the fiat section 12of the handle into the slots 21 and carrying the dashers toward thehandle until one dasher can be carried up on the cylindrical surface 13of the handle and the other down upon the cylindrical surface l. Thedashers are free to rotate and are held apart by a spacing-block. 22,which is made in two sections connected by a wire 23. The wire normallyconnects these sectious at one end of the spacing-block only and vextends beyond the opposite end of the block, 1

and the spacing-block is provided with a cen- 1 tral opening ofsuflicient size and shape to l neatly receive the liatsection 12 of thehandle. 1

' Vhen the sections of the spacing-block have been opened and thespacing-block is placed 3 on the handle at the flat section 12, theextending ends 24 of the handle-wire 23 are twisted together, thusholding the block in place; but other forms of fastening device may besubstituted, if desired.

It will be observed that when churndashers are constructed as above setforth said dashers .will turn in opposite directions and reverseautomatically with the up-and-down motion of the handle that carriesthem.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. Achurn-dashercomprisingahandlehaving a journalformed thereon for the reception of the blades, and a flattened sectionadjacent the journal and contained within the circle thereof incombination with a dasher having a central hole adapted to fit on thejournal and a slot extending from said hole to the exterior and adaptedto pass the flattened section of the handle, substantially as described.

2. A churn-dasher, comprising a handle having a journal formed thereonfor the reception of the blades, and a flattened section adjacent thejournal and contained within the circle thereof in combination with adasher formed of crossed bars recessed to in- 1 terloelgand providedwith angnlarly-disposed 1 blades forming a wheel, said wheel having a 1central hole adapted to receive the journall and a slot extending fromthis hole to the exterior and adapted to pass the flattened seet ion ofthe handle, substantially as described.

3. A churn -dasher, comprising a handle having two journals of reduceddiameter formed thereon for the reception of the wheels or blades, aflattened section between the journals and contained within the circlethereof, in combination with wheels or dashers each having a centralhole adapted to it 011 its journal, a slot extending from said hole tothe exterior and adapted to pass the flattened section of the handle,and a removable spacing washer or block between the two dashers,substantially as described.

A churn-dasher, comprising a handle having two journals of reduceddiameter formed thereon for the reception of the wheels or blades, and aflattened section between the two journals and contained within thecircle thereof, in combination with wheels or dashers each formed ofcrossed bars recessed to interlock and provided with angularly-disposedblades forming a wheel, said wheel having a central hole adapted toreceive its journal and a slot extending from the hole to the exteriorand adapted to pass the flattened section of the handle and a two-partspacingwasher adapted to be seen red by the flatten ed section of thehandle between the two wheels after the wheels are in place,substantially as described.
